ARTHUR GETS LOST : Arthur is all set for his first solo ride on a public bus. He's got the exact fare and a book to read, but one thing he didn't count on is falling asleep! When he wakes up, Arthur finds himself in a strange -- and scary -- part of town. Will he ever find his way home? And will D.W. ever forgive him for scaring her like that? ARTHUR CLEANS UP : Elwood City's park is in bad shape. There is garbage everywhere. After grumbling about it, the kids find themselves "volunteering" to clean it up. Even though it is a lot of work, in the end they all decide it feels great to make a difference. D.W. GETS LOST : If you think being lost in a humongous, super-giganto department store would scare a four-year-old, think again. Lost while searching for the earrings of her dreams, D.W. wreaks havoc as she tries to find her way home.
